Process — Loom mounting (30, 30e). Warping, Beaming —? by mill and frame. Heddling — warp entered by Fig. 89.—• RobertsLoom, Side Elevation, 1830The warp passes from warp beam (/), over roller (K), through heddles (L),through reed of batten (H); here the cloth continues over breast beam andis rolled upon cloth beam (A). WEAVING TYPES 203 Wefting. Shedding, Picking, Battening. These processes proceed as in the Drop-box-shuttlehand loom, but automatically and in uni-son, with an additional automatic beammotion, and stop weaving motion. Economic Gain In production: Introduction of steam power. Automatic and continuous shedding, picking, batten-ing and letting-off and taking-on product: Uniformly even and perfect web.
